Unilever is hosting a global online dialogue to help co-create solutions to some of the world's most pressing sustainability challenges. The Unilever Sustainable Living Lab takes place on 24 April with a focus on how to reduce environmental impacts in the home.

The lab aims to identify what we can all do as businesses, governments, NGOs and consumers, to tackle issues such as reducing household water use in water scarce areas, finding new ways of recycling where there is no existing recycling infrastructure, and reducing the environmental impacts of hot water in the home. Last year, more than 2,000 people from 77 countries registered for the first Unilever Sustainable Living Lab and nearly 4,000 comments were posted.

This year, there will be a series of sessions split into morning and afternoon at the following times:

New Dehli (IST)

12.30am - 3.30pm

8.30pm -11.30pm

London (BST)

8am - 11am

4pm - 7pm

New York (ET)

3am - 7am

11am - 2pm

The lab will be kept open for viewing for two weeks after the event, as a resource for participants.
